Fix steal-tools bundle docs

Remove references to `deps-bundle-dest` and `dev-bundle-dest`; the
attributes `dev-bundle` and `deps-bundle` can be passed a string to the
path where the dev-bundle module is located.

 Unlike a **dependencies bundle**, a **development bundle** has to be loaded before [StealJS configMain](StealJS.config.configMain) is loaded. In order to do that, StealJS provides a `dev-bundle` propert that you can set to the script tag so it loads the bundle correctly, like this:
 
 ```
-<script src="./node_modules/steal/steal.js" dev-bundle dev-bundle-dest="my-dev-bundle/"></script>

 You will get faster load times with **development bundles**, with the downside that you will need to generate the bundle each time your config module changes or your application might no load at all.
